MOSCOW: Militants in the post-Soviet region are attempting to obtain nuclear materials for use in attacks, Russia’s security services chief said on Wednesday. “We have information showing that terrorists are continuing attempts to gain access to nuclear materials (and) biological and chemical components,” Alexander Bortnikov said at a press conference in Yekaterinburg, the RIA Novosti news agency reported. “We are constantly paying attention to this problem,” he said. Russia’s Federal Security Service (FSB) has worked with security forces of other countries in the post-Soviet CIS region to prevent a number of attacks, Bortnikov said. “A number of joint special operations allowed us to foil the plans of terrorists to carry out acts on the territories of CIS countries,” he said. Security forces are investigating the case of a man who attempted to carry out 12 attacks in Moscow, he said. “Last year, we managed to intercept a channel of supply to Moscow of 15 kilogrammes of TNT and hexogen and detain an agent who planned to carry out 12 terrorist attacks in Moscow. He has been charged.”
